McHenry County Department of Planning and Development Flood Assistance

Damage Assessment

The County is responsible for reporting residential and commercial property damage to state and federal emergency management agencies. This data helps the county and property owners qualify for state and federal assistance programs. County employees and volunteers will be out in the neighborhoods assessing property damage. If we missed you, please report any damage to your property using our on-line damage assessment form or by calling (815) 334-4560. Be sure to indicate if you have flood insurance as this information is critical for state and federal assistance programs.

Building Repairs

Flood damaged personal items and building materials should be removed from habitable structures as soon as possible to reduce the chance of mold growth. This includes removal of damaged carpeting and drywall, which can proceed without permit approvals. Most repair activities will require building and stormwater management reviews and permits. This includes the replacement of damaged carpeting and drywall. Permits are also required for other repairs, including, but not limited to, structural, electrical, plumbing, and the replacement of damaged heating and cooling equipment and water heaters. Any site grading or modifications to address flood damage or erosion may also require stormwater reviews and permits. These reviews and permits are required to ensure compliance with local and federal regulations Failure to follow these procedures can jeopardize the availability of flood insurance. 

For unincorporated areas of the county, permit fees may be waived for property owners repairing flood damaged homes and businesses. Please review the department’s application forms and checklists prior to applying for permits.  For additional information contact the Department of Planning and Development at (815) 334-4560.

For incorporated areas of the county, please contact your respective municipality for more information on the permitting process.  A list of community contacts may be found here.

Local Drainage Problems

Local drainage problems can be reported using the department’s request for enforcement form. The County does not have a public works department with staff and equipment to fix drainage problems on private property. The department will dispatch an inspector to review the problem and provide advice regarding possible solutions. In certain instances where the drainage problem has been caused by unpermitted development, we can require the responsible party to remedy the situation. 

The Planning and Development Department processes and issues various types of permits and approvals in unincorporated McHenry County.

If your property is located in a village or city, please contact their office. A list of communities and contacts may be found here
